  "message": "[Hexagon] Fix extractHvxSubvectorPred shuffle mask for small predicates (#181364)\n\nThe loop generating the shuffle mask in extractHvxSubvectorPred used\nHwLen/ResLen as the iteration count, but each iteration produces 8\nelements (ResLen * Rep where Rep \u003d 8/ResLen). This means the total mask\nsize was (HwLen/ResLen) * 8, which only equals HwLen when ResLen \u003d\u003d 8.\nFor smaller predicate subvectors (e.g., \u003c4 x i1\u003e or \u003c2 x i1\u003e), the mask\nwas too large, causing an assertion failure in getVectorShuffle.\n\nFix by using HwLen/8 as the loop bound, which correctly produces HwLen\nelements regardless of ResLen.",
